Head gasket to cc

What is a ball park figure on how much cc i will lose for every 10th. Bigger on the head gasket thickness ??

 

Head Gasket

What bore size are we talking about. That will make a difference.

 

If you are asking for the CC (cubic centimeter) change it is easy to calculate.
(gasket bore/2) squared x pi (3.1416) x thickness (or change in thickness) of gasket x 16.387.

example 4.310 bore/2 = 2.155
2.155 x 2.155= 4.644025
4.644025 x 3.1416=14.58963
14.58963 x .010 (gasket thickness change)= .1458963 cu in.
.1458963 x 16.387 = 2.391 cc (cubic centimeters)

 

If you are asking for compression ratio change it will depend on the bore, stroke, and chamber volume. As an example, on a 4.28 bore x 4.50 stroke hemi with a 176 cc chamber, .010 head gasket change makes about .24 - .25 change in compression ratio.

 

Compression change..4.375 bore , 3.75 stroke , 43th gasket !! Going to a 60 or 70th...

Santo....
on a 4.375 bore when i cc'd our motor this winter .....for every .010 on the gasket, you lose or gain right at 1/3 of a point. .050 gasket with 12 to 1, go to a .060 gasket and you have right at 11.7 to 1. give me a call some evening when you have time.
